The clue just now directly covered a rock behind Hong Yi. It instantly seemed to be poured with sulfuric acid, corroded and traces were corroded, emitting a pungent smell. +◆

Seeing this scene, Hong Yi turned dark and thought that if he hid a little slower, he would be hit directly and would be seriously injured. He would be trapped by a spider web that is comparable to a steel wire, and he would not even be able to run away.

He quickly thought about tactics in his mind, and immediately took out an arrow and pulled the bow and shot it.

This is an ordinary alloy arrow. The power is almost the same as that of a bullet at this distance, but the next moment, something that shocked Hong Yi. This arrow was actually bounced open by the shell of the spider mutant. The alloy arrow only splashed a piece of Mars on it, leaving a dent that was neither deep nor shallow.

"Damn, this guy's shell is almost the same as the steel shell mutant!" Hong Yi knew that he had encountered a tough guy, and the next moment, another spider silk sprayed over. Hong Yi hurriedly moved quickly to avoid it, but the area of ​​the passage was very small, and Hong Yi's speed was limited, so he could only barely avoid it.

Afterwards, Hong Yi suddenly felt the danger coming, but hurriedly dodged, but saw that the spider mutant was extremely fast and actually rushed over and killed himself with his sharp insect limbs.

Several long legs like blades of spider mutants flew up and down at this moment. Once they were stabbed, they would definitely be penetrated. If they were not dead, they would definitely lose their combat effectiveness immediately.

This spider mutant obviously has the strength of a third-level mutant in White Star. If it were someone else, he would have been knocked down long ago, that is, Hong Yi is extremely powerful. Although he is not good at melee combat, he has the skills to deal with this situation.

"Fireball, kill!"

Hong Yi quickly used the fireball ring to condense a ball of fire and smashed it out. The spider mutant obviously did not expect it to be smashed to a solid point. The fireball turned into a ball of flame, burning it to a squeak.

Although this spider mutant has a strong bulletproof shell, it was afraid of flames, and it was burned black. It immediately escaped and drilled into the previous hole. The splashing flames ignited some spider webs around it. Although these spider webs were extremely tough, they were also afraid of flame burning. Seeing this, Hong Yi immediately had an idea and condensed a fireball again, smashing directly towards the passage in front of which was blocked by layers of spider webs.

boom!

The flames had an unexpected effect. The spider silks that were tough enough to withstand the alloy machetes and had a corrosion effect broke and burned one after another under the burning of the flames. After a while, a gap was burned into the passage, enough for Hong Yi to enter.

Ignoring the flames around him, Hong Yi quickly entered, passing through the layers of spider webs that were four or five meters long, and reaching the internal cave.

After entering, Hong Yi discovered that there was another world inside.

First of all, the cave below is very big, just like an underground world. The height of the cave alone is more than twenty meters. Hong Yi looked around and saw many corpses of spider mutants. Of course, the size of these spider mutants is not as big as the one that attacked him just now, but it is not small anymore. The smallest ones are the size of a washbasin. So many spiders make people goosebumps when they see it.

There are many types of spider mutants here. Even through the mutant database of the adjutant's intelligence brain, Hong Yi could only barely recognize a few.

There are 'defenders' with hard shells, 'predators' who can spray venom, and some spider mutants with unknown information.

Some of these variants have been poached brain crystals, while others have not.

Hong Yi walked forward for a while and felt something strange was moving beside him. He immediately used a bow to shoot an arrow. An alloy arrow shot a "Plower" who was about to sneak attack and spew out the venom like lightning.

"Kill the spider mutant and get 1 experience point!"

Hong Yi looked at his experience value. As long as he went to 19 o'clock, he could upgrade the Shadow Walker to level 1 and obtain a skill.

This time when Hong Yi entered the spider's nest, he didn't know what he would encounter. After all, even Wu Tong, the mentor-level evolver, was trapped and unable to get out. There was also the giant spider mutant that reached the third level of the White Star. This monster was obviously very good at sneak attacks and escaped when it encountered an attack, which was very difficult. So for Hong Yi, it would be more beneficial to him to get more trump cards.

After walking here for a while, seven or eight spider mutants had already attacked, but all of them were shot and killed by Hong Yi, and the arrows used were all ordinary alloy arrows.

This time, Hong Yi only brought a quiver's energy arrow. Who would have thought that an ordinary training course would encounter such an accident? It can be said that Hong Yi was not prepared enough, and even Yanbi's location was more than 70 kilometers away from here at this moment, so Hong Yi did not summon Yanbi to come.

A large area of ​​corrosive spider silk appeared in front of it, dividing the entire cave into two halves. Moreover, the number of spider silk here is simply outrageous. It is actually a wall that was once difficult to break through.

And on this huge spider web, Hong Yi saw a huge spider mutant lying on it, and many compound eyes were staring at him at this moment.

"It's that guy just now!" Hong Yi saw that the giant spider mutant was charred black, and immediately recognized that it was the mutant that had sneaked into him before.

When it saw Hong Yi coming, it immediately let out a few screams. The sound was very harsh, like someone stabbed your eardrum with a needle, which was unbearable.

Hong Yi was not polite either. He endured the stinging pain of his eardrums and took out an energy arrow to inject fire energy, and shot it with a bow.

The spider mutant obviously knew it was powerful and hurriedly dodged, but its speed was still one step slower. The arrow was extremely fast and directly pierced its back. The hot fire could inject from the wound, burning the internal organs of the spider mutant in just a moment.

The spider mutant let out an unprecedented scream, and half of its body was almost burned, but it was hard to believe that it was still alive and was not killed by this arrow, but climbed quickly and escaped from a hole at the top.

Hong Yi shook his head. He didn't expect that the spider's vitality was so tenacious. If it were other mutants, they would have been burned to death long ago.

However, this arrow was enough to make the opponent lose half of his life. At least in a short time, this elusive spider mutant would not be able to sneak attack again. Moreover, before the opponent escaped, Hong Yi hit the opponent with a "hunter mark". In this way, Hong Yi already knew the opponent's position. In other words, if this mutant came to sneak attack again, Hong Yi was sure to shoot him as soon as possible.

Put the longbow away, Hong Yi condensed a fireball and opened the way, boiling the corrosive spider silk blocking the front into a channel and moving forward slowly.

These spider silks that block the passage obviously appeared in the past few hours. Otherwise, Wu Tong and the others would not have passed through here before. Maybe it was because they found that the retreat path was blocked and they could not leave after entering here.

Looking at the top cave where the spider escaped, Hong Yi shook his head. Only spiders could climb up at this height, and it was impossible to use these corroded spider silks, unless they were killed.

After condensing a full three fireballs, Hong Yi opened a channel. However, releasing the fireballs continuously also consumed Hong Yi's biological energy. If it was not necessary, Hong Yi would no longer use biological fire energy.

Along the way, Hong Yi did not find any fresh human corpses. You should know that including the previous group of students, there were at least thirteen humans entering here, including Wu Tong, Li Ming and Song Hui.

But Hong Yi did not find the body, which means that these people may still be alive.

There is almost no light outside here, only some inexplicable stones and plants emit extremely weak biological light. Hong Yi had long controlled the adjutant's intelligence to switch to night vision, but even so, the visibility of the vision was greatly limited. At most, the scenery was only seen more than ten meters away. No matter how far it was, it was pitch black.

In this environment, if you don’t have an adjutant’s intelligence and rely solely on humans’ own five senses, it will definitely be difficult to move forward.

Several spider mutants hidden in the dark were waiting for an opportunity to ambush Hong Yi, but they were all shot and killed by Hong Yi at a long distance. It can be said that as long as they are mutants entering Hong Yi's vision, Hong Yi will be shot and killed.

There are two benefits to doing this: one is to eliminate dangers and the other is to gain experience.

Finally, after shooting a spider mutant, Hong Yi accumulated enough experience points and immediately upgraded the "Shadow Walker" skill tree.

"Shadowwalker rose to level 1."

"Bone strength is increased by 1 point, muscle strength is increased by 1 point, agility is increased by 1 point."

"Unlock the skill ‘Blade Assassination’, the next level requires 200 experience points."

Hong Yi felt that a large amount of data flowed into his brain, including the method of using the skill "Shibition Assassination". There is no doubt that this is the melee skill that Hong Yi lacks most now.

To put it bluntly, the assassination of a hand-blade is a short weapon combat method, including a variety of stabbings. The weapons suitable for this skill are undoubtedly weapons such as daggers.

Pulling out the alloy dagger at his waist and holding it in his hand, Hong Yi felt completely different from the feeling of holding a dagger before.

It was very familiar. When Hong Yi moved his finger, the dagger turned around in his hand, and then held it steadily. The forehand can be changed very skillfully, just like after a long period of practice.

It won't fall down inadvertently, and it won't hurt yourself.

At this moment, a spider mutant in the darkness slowly approached Hong Yi. This was a defender spider with a hard shell, fast speed, good at flying and biting. At this moment, it slowly climbed to a range of four or five meters away from Hong Yi, and suddenly accelerated and pounced on it. With its speed and strength, it was enough to knock an ordinary person down, and at the same time, it used a sharp mouthpart to bite the human skin and bones.
